Very nice composition, but it lacks a sharpness a bit on the focused flower

Probably it is caused by the lens (I have it as well) which has some small issues with macro kind of picture. Also, ss you might noticed, the bokeh is not that very quality I love (probably you too) on Nikkor Micro 105 mm.

But on the other hand, it gives a painting kind of look and composition is like according the rule book
